TIE FOR MINE-RAILVVAYS.

Application filed July 30, 1320.

To all whom it may concern:

Be it known that I, FRANK C. MAYER, a citizen of the United States, and a resident of Bridgeville, in the county of Allegheny and State of Pennsylvania, have'invented a new and Improved Tie for MineR-ailways, of which the following is a full, clear, and exact description.

This invention relates to railway track appliances and has particular reference to railways for mines, tram cars, or other railways of a relatively temporary nature as distinguished from standard heavy traffie, such as steam or electric railways.

Among the objects of the invention is to provide a new type of railway ties the same being applicable especially for making a reliable joint between metal and wooden rails.

Another object of the invention is to provide a railway tie adapted for the direct application thereto of either metal or wooden rails.

With the foregoing and other objects in view the invention consists in the'arrangement and combination of parts hereinafter described and claimed. and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in Which Figure 1 is a plan view of one end pol.- tion of my improved tie showing secured thereto the meeting ends of metal and Wooden rails.

Figs. 2 and 3 are vertical transverse sec tions on the corresponding lines of Fig: 1.

Fig. 4 is a vertical transverse section of the tie alone on the line l l of Fig. 2.

Referring now more specifically to the drawings I show my tie 10 as comprising amain body portion shown as flat but obviously capable of being made of any suitable design in cross section. This tie may be made of any suitable material, but I have found for the best practice that malleable iron is quite suitable, being relatively cheap and of a strong; tough nature. Such material also lends itself immediately for the making of the special features constituting attachment means for the rails. While I show but one end Specification of Letters Patent.

of the tie it will be understood that each he will be made complete a unit with similar ends for the attachment of male at the usual distance apart. and while I show and describe but one series of at techment means for the rails such description will be understood as being ap licable to both ends of the tie. A 1

11 indicates pair of spurs carried by the upper surface of the tie and adjacent to the edges thereof. These spurs are notched or undercut at 12 at one side to receive one edge of the base flange 13 of a metal rail 14. The spurs are so located as to automatically establish the proper position for said rail with respect to the tie and the rail at the opposlte end of the tie. These spurs are arranged in pairs and similarly located with respect to the end of the tie and being in pairs they are adapted for cooperation with the meeting ends of two adjacent rails, but if a single rail spans the tie the presence of the two spurs is no objection but rather an advantage in favor of strength. The upper ends or points of the spurs are somewhat sharpened. i

The tie 10 is provided with holes 15 preferably arranged one for each spur l1 and at about the same distance from the edge of the tie. These holes 15 are located on the opposite side of the line of the rails 14% from the spurs. andfor the clamping of a metal rail to the tie in connection with a spur 11 I employ clamping block 16 in connection with bolt 17, or its equivalent, passing upward through a hole 15 and through said block. Each block 16 is provided with a square end 16 while the other end 16" is somewhat longer than the square end and conforms to the side of the metal rail and having an undercut 16 to acccmmodate the edge of the base flange opposite the one projectin beneath thespur 11. The block 16 being i onsiderable width and fitting squarely against both the base flange and the web of the rail is held securely from rotation around the bolt 17 when the nut 17 of the bolt is tightened. Consequently any endwise shifting of the rail 14 would tend to be resisted by the cramping of the block in addition to the normal frictional contact between the rail and all of the parts cotiperating therewith.

18 indicates a wooden rail such as is commonly used in mines or other temporary track structures. In the usual practice it is a difficult matter to secure the abutting end of a wooden rail in place to constitute a continuation of a metal rail; With my improvement, however, such attachment of a wooden rail is both expeditious and reliable. To this end I provide a flange 19 shown as constituting a rigid or integral part of a tie between the extreme end thereof and the spurs. T his flange is parallel to the line of the rails and is provided preferably with an inner surface perpendicular to the top surface of the tie. The outer surface of the flange may be inclined or battering for the sake of maximum strength. The flange, however, is

provided with a plurality of holes 20 the axes of which are perpendicular to the rails and. parallel to the tie. The rail '18 as usually made and used. is of the same height as the metal rail, but is somewhat wider giving' a maximum degree of firmness and strength. The width of the rail 18 corresponds approximately to the spacing of the flange 19 orin practice he rail 18 may be either reduced or increased in widthto es tablish the proper alinement of the rails. Each hole 20 is adapted to receive spike 21 which may be driven through the hole and into the side of the wooden rail remote from the line of the metal rail. The bottom of the rail 18 receives the spur 11. This may be provided for either by notching or recessing the rail at 18 or the same result may be accomplished by simply placing the rail on top of the spike and striking down upon the rail with sledge causing the spur to be driven relatively upward into the rail. Thus the spur or spurs will serve to substantially holdthe wooden rail from. ondwise movement. Lateral movement of the rail toward the end of the tie is prevented by the flange 19. The lifting of the rail is prevented by the spike or spikes 21. Movement of the rail away from. the flange or toward the center of the tie is prevented by means of the block or blocks 16 applied with their square ends 16. squarely against theinner verticalside of the rail. See Fig.3. The blocks 16 being made preferably all alike so that either end thereof may be employed for gripping contact with a rail absolute reliability as well as facility in connecting the rails to the ties is assured. From the foregoing description it will be obvious that the same typeof ties may be employed for any portion of the road and for the attachment of either all metal rails or all wooden rails, or any desired combination thereof. It is manifest that the ties may be employed for rail joints as well as for supporting any other portions of the rails, and that no fish plates or other attachment means, auxiliary to the devices above described, are required.

"I claim:

1. The herein described metal railway tie having a rigid spur projecting upward from its upper surface adjacent to the line of the rails, a member projecting upward from the tie between the spur and the end of the tie, and clamping means cooperating with the tie upon the opposite side of the spur from the upwardly projecting member. I
